Final answer:
More force applied to one end of the seesaw results in more motion on the opposite side due to the principles of physics involving levers and moments. In the case of children on a seesaw, the heavier child should sit closer to the fulcrum to achieve balance. The correct option is c) More motion resulted on the other side of the seesaw.
Step-by-step explanation:
When more force was applied to one end of the seesaw, more motion resulted on the other side of the seesaw. This is based on the principles of levers and fulcrums in physics which dictates that applying a force on one side will result in a motion on the opposite side, assuming that the seesaw is balanced and free to move. This is also consistent with the principle of moments where the forces on either side of the fulcrum must be balanced for equilibrium.
Regarding the GRASP CHECK, for two children of different weights to be balanced on a seesaw, the heavier child must sit closer to the fulcrum. This principle is based on the condition for equilibrium that requires balancing the moments around the pivot point. The child's weight multiplied by the distance from the pivot must equal each other for both children to be in balance, as described in the solution for part (b) of the discussion.
